Location: Worlds of Fun is located off Highway 435 in Kansas City, Missouri.
History: Worlds of Fun was opened on May 26, 1973, at a cost of 25 million dollars. Loosely themed around the Jules Verne book, Around the World in Eighty Days, the park was founded by Hunt Midwest Company. In 1982, Hunt Midwest bought a nearby waterpark, Oceans of Fun. In 2013, Worlds of Fun and Oceans of Fun were combined to a one ticket admission, providing all guests with access to 235 acres of amusement and water rides.
Hours: Worlds of Fun is open from April through Halloween.
Tickets: Buy and print online. Always try to buy your tickets in advance, to save time when you get to the park.
Reservations: Worlds of Fun sells “Fast Lane” cards that save riders’ time by allowing them to bypass the majority of wait for most of rides and attractions including Mamba, Prowler, and Patriot. Ride as many times as you want all day long.
Strategy: Most visitors tend to begin the day with Prowler, the hottest attraction in the park. Use that tendency to your advantage and head to the Patriot first. After that, try the Dragons. Then work your way back to the Prowler. After riding the Prowler, there is only one coaster left, Mamba. Hit it next. If the park is not very crowded, you can ride Boomerang on the way to Mamba. After riding Mamba, head back for a ride on the Wolf. By then you will have tried most of the popular rides and attractions in the shortest possible time.
News: In 2017, Worlds of Fun is adding Steel Hawk, a ride that will take guests up 301 feet in the air and spin them at a 45-degree angle for a 60-second flight. Wait to have a try!

7 . Far from the land of Antarctica, a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein. Or AFGP.

Even plant can run a fever, especially when they’re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3, 000 feet away straight up. A decade ago, adopting the infrared （红外线）scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide （杀虫剂）spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest （害虫）problems.
Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3, 000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running“fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.
The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long - term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States, ” says George Oerther of Texas A & M. Ray Jackson , who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only ff Paley finds the financial backing which he failed to obtain 10 years ago.
